Model 26 Integrated Pancake Frisker
Introduction
Frisking people and objects for alpha and beta contamination
has always been a little awkward because manipulation of the
cable, detector, and electronics required the use of both hands.
The cable-less Ludlum Model 26 consolidates the electronics
and the detector into one ergonomic housing. This optimized
configuration incorporates a standard 15.51 cm² GM pancake
probe, loud audio “click” output, and large auto-ranging LCD
display with automatic back lighting into one convenient package,
making it easier than ever to detect contamination.
Operation is kept extremely simple through the use of just two
buttons. A useful feature employed in the design is the MAX mode,
which captures the highest or peak count rate. It is particularly
convenient whenever the display is not directly visible. The scaler
mode, with a preset count time, allows the user to take a discrete
measurement. This system also incorporates low power circuitry,
delivering hundreds of hours of use with just two standard “AA”
size batteries. The calibrator can protect parameters (cps/cpm,
response time, alarm points, and scaler time) or allow the user to
adjust them.

Model 26-1 Integrated Pancake Frisker
Introduction
Optimized configuration of Model 26-Series includes a standard
15 cm² GM pancake, loud audible “click” output, and large autoranging LCD display with automatic backlighting. Model 26-1 has
the addition of a Units button that can display measurements in terms
of mR/hr, µSv/h, dpm, or Bq. These features are combined in one
convenient package making it easier than ever to detect alpha/beta
contamination and measure gamma fields on personnel and objects.
Operation of the Model 26-1 is kept simple through the use of just
three buttons that are strategically placed for one-handed operation.
Three modes of operation, RATE, MAX, and COUNT, are available.
The user-selected units can display results in a measurement of
scaler counts, activity (disintegrations), time-averaged rates, or even
accumulated dose. In addition, the optionally-available energycompensation filters can correct the energy response for exposure or
ambient equivalent dose. See Model L-4002-1066 Exposure Filter
Kit and Model L 2002-1050 Ambient Dose Equivalent Filter Kit.
Low-power circuitry means two standard “AA” sized batteries
deliver hundreds of hours of instrument operation. Other features
include a backlight triggered by low-level ambient lighting (may
be configured for “Continuous On” operation) and a click’ audio
that may be silenced for both RATE and MAX modes.

RADIATION SAFETY
Survey Meters (Ion Chambers)
Model 9DP-1 Pressurized Ionization Chamber Survey Meter
Introduction
The Ludlum Model 9DP-1 ion chamber meter is specially
designed for radiography work where pulsed fields are being
measured. This instrument correctly integrates 50 nanosecond
pulses (and wider) that other systems typically miss or measure
inaccurately. This instrument measures both exposure and
exposure rate and can simultaneously display the exposure
rate with either the integrated value or highest rate seen by
the instrument. The integrated value can be reset (if desired)
using one of the four convenient front-panel mounted buttons.
The buttons also control instrument power, function selection,
setting the speaker volume, and acknowledging alarms.
The detector chamber is only pressurized to 1.7 atmospheres
(20 psi), thus avoiding all (USA) HAZMAT concerns for
shipping and handling. The stunning 256-color, bit-mapped
display provides an optimized presentation of the data and
is accompanied with icons informing the user of the active
functions and instrument status. Alarms are manifested using
color changes on the display and an acknowledgeable audio
output. Measurements can be logged to an industry standard,
USB thumb drive plugged into the instrument USB port. Data
are written in CSV format for convenient retrieval by a PC
spreadsheet or database program.

RADIATION SAFETY
Survey Meters (Ion Chambers)
Model 9DP* Pressurized Ionization Chamber Survey Meter
Part Number: 48-3942
Introduction
The ambient dose version of the Model 9DP, designated as
Model 9DP*, is a highly sensitive pressurized ion chamber
meter that provides a measurement of exposure and exposure
rate that is measured and displayed in accordance with, and
based on, the ICRU (International Commission on Radiation
Units) 30 cm tissue equivalent sphere. Simply described, the
definition of ambient dose equivalent is the dose equivalent
readout that would be measured at a (human) tissue depth
of 10 mm. This requires a special ion chamber that can
provide a conversion of the (air kerma) exposure rate to
provide the ambient dose and dose rate. Just like the Model
9DP, the Model 9DP* can simultaneously display the *rate,
integrated value, and highest *rate seen by the instrument.
The integrated value can be reset (if desired) using one of
the four convenient front panel mounted buttons.
The stunning 256K color, bit-mapped display provides an
optimized presentation of the data, and it is accompanied
with icons informing the user of the active functions and
instrument status. All logged data can be written in CSV
format to a plugged-in industry standard USB thumb drive
for convenient retrieval by a PC spreadsheet or database
program. Alarms are manifested using color changes on the
display and an acknowledgeable audio output.

Model 23 mrem Electronic Personal Dosimeter
Introduction
The Ludlum Model 23 mrem Electronic Personal Dosimeter
is a compact and lightweight (2.1 oz) pen-type Personal
Dosimeter. It is ideal for the measurement and general
monitoring of gamma and x-ray radiation in medical
and laboratory environments, as well as any controlled
or restricted area where personal radiation monitoring is
required. The unit is sensitive to a wide range of energies
from: 35 keV to 3 MeV. Dose, Dose Equivalent Rate and
Alarm values are easily seen on the 4 digit LCD Screen. An
audible alarm is activated if the dose or dose rate exceeds
the preset value of the dosimeter. The alarm set points are
adjustable from the face of the EPDi unit.
For users with multiple EPD units the optional Model 23 mrem
Reader/Software kit can be used to quickly take data directly
from the EPDi Dosimeter via Infrared communication, to the
users PC. The software also allows the user to set or change

Model 375P-1000 Waste Survey Monitor
Introduction
The Ludlum 375P-1000 Waste Survey Monitor is ideal for inspecting outgoing trash and/or medical waste for possible lowlevel radioisotope contamination. The system continuously monitors background levels and will alert the user when the
infrared sensors detect a contaminated object. Once the object is removed, the system will return to normal (background) monitoring.
The Waste Survey Monitor will easily pay for itself in the prevention of just one contaminated shipment. Fines assessed by the
various regulatory agencies are significantly more than the cost of installing this monitor at your facility.
Options include a red strobe light alarm and a date and time printer to document the occurrence of the detected contaminant.

Model 375P-336 Surface Contamination Monitor
Introduction
The Model 375P-336 is a Digital Model 375 Controller coupled
to two 2753 cm (168 in) plastic scintillation detectors. This
instrument is ideal for monitoring personnel or laundry for possible
contamination in the nuclear medicine department. The monitor
may also be used as a radiation contamination triage device to alert
emergency department personnel of potentially contaminated
patients or equipment coming into the emergency room.
Using hand held instruments for inspecting items can, in many cases,
be too time-consuming. The Model 375P-336 allows a more rapid
and uniform inspection by placing two relatively large scintillation
detectors in proximity to the incoming or outgoing articles
undergoing inspection. Both detectors are continuously monitored
by the digital controller so any offending item can immediately
trigger an alarm. Alarm conditions can be set up to automatically
halt production conveyance devices, notify the central office,
and even alert key personnel to initiate an immediate response.
Ludlum Measurements encourages the use of an optional rail, Part
Number 2311167, in those environments where equipment, carts,
or other traffic might strike and damage the detectors.

The new Ludlum L-435 HVL Filter Holder is designed to
simplify the routine HVL measurement process. For years the
method of attaching the HVL filters to the X-ray collimator
involved using quantities of medical/surgical tape. While tape
does the job, it also tends to destroy the thinner aluminum
filters; particularly the high purity mammography filters.
The copper filter is permanently bonded to the polycarbonate
base material. The copper filter is covered with an acrylic
pocket. The pocket, open on one side, will hold all of the
provided filters*. The polycarbonate material is easily cut with
a standard utility knife or shears to accommodate the two most

Dose Meter / Exposure Time Meter
KVp Meter and Exposure Time Meters
The Ludlum Model 8900 RS Dose Meter / Exposure Time Meter
is specifically designed to measure X-ray dose. The Model
8900 can also be used for dental X-ray units, radiographic and
fluoroscopic X-rays.
This kVp Meter and Exposure Time Meter directly measure
peak kV from the X-ray head. A simple push of the button
will display the exposure time. The Model L-815 and Model
L-815LR share the same attributes with the exception of range:
the Model L-815LR is calibrated to detect a lower range of energy.
Both are reliable, battery-operated, easy-to-use, compact, and
cost-effective instruments for calculating peak kV (kVp)
voltage of tungsten-generated X-ray equipment and also
measuring exposure time. Detectors are improved to provide
greater range and more stable, repeatable measurements. In
addition, an android application has been developed so that
the instrument readings can be sent directly to your mobile
device’s display.
The Model 8900 RS automatically resets at the beginning of each
exposure, holding the reading until the next exposure. There is
no need to reset the meter before each measurement.
The Model 8900 RS is a small hand held battery operated unit.
Each X-ray exposure is displayed on a 2x12 digit liquid crystal
display (LCD). The operator can select between English (mR)
and SI (μGy) units. The instrument works for half-wave, fullwave, multiphase or DC (constant potential) X-ray generators.
When a measurement is being made, the Model 8900 has the
capability of automatically determining the type of X-ray that is
being measured.

Rotating Spoke Test Tool
Introduction
The Ludlum Model L-629 Rotating Spoke Test Tool is
designed to evaluate the performance of the fluoroscopic
imaging systems. The tool demonstrates screen image lag,
motion blur, contrast, and related distortions encountered
in fluoroscopic examinations. **
When combined with aluminum or acrylic block
attenuators the rotating spoke test tool provides the user
with a means to simulate the movement of guide wires
and radiopaque catheters, seen in angiography or cardiac
catheterization patient procedures.
The rotating spoke test pattern consists of a circular 14 cm
(5.5 in.) diameter acrylic disk with steel 12 wires arranged
on its surface in 30 degree intervals. The wire diameters
range from 0.51 mm (0.02 in.) to 0.127 mm (0.005 in.).
There are two wires of each size directly opposite each
other on the disk. Lead numbers (1–6) appear on each half
of the disk near the perimeter. The disk is mounted on a
synchronous motor with a speed of 30 RPM to simulate
movement of wires.
Grid Alignment Test Kit
Introduction
The Ludlum Model L-644 Grid Alignment Test Kit is
designed to confirm that the proper centering and height
uniformity of a standard or focused grid is correctly
aligned with the central axis of the X-ray beam.
The test procedure is simple and requires that the holed
test plate is centered to the X-ray table and positioned such
that the length of the tool is perpendicular to the direction
of the grid lines. One exposure is then made centered
over each hole in the test plate. After processing, the
film (image) is examined for potential changes in optical
density. A properly centered and level grid should provide
five equal densities on the test film (image).
Specifications
The test kit includes one plate, 22.9 x 8.9 cm (9 x 3.5 in.),
with five test holes. There are also two blocking plates,
which measure 8.9 x 6.0 cm (3.5 x 2.4 in.). All three plates
are made of 0.16 cm (0.06 in.) thick lead encased in acrylic
material for ease of handling.
The visibility of smaller diameter wires 0.356 mm (0.014
in. or less) will confirm the system performance. [3.56 mm
(0.14 in.) is a common guide wire size]

Fluoroscopic Alignment Device
Introduction
The Ludlum Fluoroscopic Beam Alignment device consists of
an aluminum plate with four sliding brass strips set in recessed
channels. The strips define the border or visible area of the image
receptor. A plastic overlay prevents any vertical displacement of
the brass strips. Holes drilled in half-inch intervals are filled with
higher density material for visibility through the brass strips.
The device, when placed in the center of the image receptor,
is designed to correct or optimize fluoroscopic collimation.
Any portion of the fluoroscopic field that falls outside the image
receptor does not contribute to the useful image and can lead to
unnecessary exposure to the patient. This very simple but critical
measurement will identify a misaligned fluoroscopic system.
Fluoroscopic Resolution Test Tools
Introduction
The Fluoroscopic Resolution Test Tool is a plastic plate
containing eight groups of copper and brass mesh screening.
Three models are offered, each with different resolutions for
standard, medium, and high-resolution ranges covering from 16
up to 150 lines per inch (LPI). (See table below.) The screens are
arranged in an irregular and non-sequential rotation to permit
better visualization of the different resolution patterns.
These test tools provide a quick check on Image Intensifier or
video system resolution.

of processor performance, fixer retention, image quality,
film screen contact and compression paddle consistency.
The kit contains the necessary items to implement a QA
program that is compliant with FDA/ MQSA regulations
and ACR recommendations.
PROCEDURE:
Use any existing approximately-sized 25 cm x 25 cm x 2 cm
Acrylic or Aluminum Plate as a base support
Kit Features:
• Mammographic Accreditation Phantom
• Lint free wipes
• Digital thermometer
• Analog Scale
• Hypo test kit
• Film contact test tool
• Sensitometer
• Densitometer
Place Support Plate on Bucky. Note: Plate should be large
enough to cover image receptor. Place the Test Object being
sure that the plate is not resting on any corner or raised edges
of the Bucky assembly, on the support plate, as if positioning
the breast. Align the straight edge of the test object with chest
wall edge of the compression paddle. Center the (foam) test
object left or right so it is centered to the compression paddle.
(For a Flexible sliding paddle, first center the paddle.)
Apply the compression force as required (typically 11.3–12.2
kg or 25–27 lb). Use the Telescoping Gauge to locate the
lowest corner of the compression paddle, closest to the edge of
the support plate. Use the set screw on the Telescoping Gauge
to lock the gauge pin in position at the measured distance. In
the event that the gauge pin is fully extended, use additional
adjustment blocks the extend the reach of the Telescopic
Gauge pin.
If the deflection of the paddle exceeds the limits of the
measured distance, the Paddle should be replaced.

Dual Source Scatter Phantom
The Model L-840 simulates in-vivo scatter
conditions required to measure gamma camera
deadtime. Deadtime is the interval in which
a gamma camera, while processing incident
radiation, is insensitive to additional radiation.
Measurement of this phenomena is important
because, during higher count rates, losses of data
during the ‘deadtime’ degrade the quantitative
data. Accurate measurement allows for the
mathematical correction of the deadtime losses.

The Model L-820 and L-890 are ideal for daily/weekly QA
checks of scintillation camera performance. The Bar and
Test Pattern Phantoms measure intrinsic and collimator
spatial resolution (ability to see small objects), and
spatial linearity (ability to correctly position image data)
confirming the gamma camera’s overall ability to identify
and properly display small anatomic objects.
Each of the sets of parallel lines is precisely machined onto
a plastic sheet. The lines are filled (cast) with Cerrobend®
high-density metal alloy. This causes the gamma radiation
to be attenuated, thereby providing the QA image.
The Phantoms are easy to use and satisfy most regulatory
quality control requirements for intrinsic resolution. By
checking the gamma camera’s resolution on a routine basis
with either of these phantoms, it will be possible to make
quick adjustments to insure the consistent quality of the
images being taken from the data that is collected.
